Neodymium nimwe mubintu bifatika byisi bidafite ishingiro

Mu 1839, Igisuwede Cgmosander yavumbuye imvange ya Lanthanam (LAN) na Puseoodmium (PU) na Neodymium (nǚ).

Nyuma yibyo, chimiste kwisi yose yitaye cyane kugirango batandukane ibintu bishya byo guhirika ibintu bidasanzwe byavumbuye.

Mu 1885, AvwelsBach, Umunyamerika, yavumbuye Prasiodymium na Neodeymium kuva mu ruvange rwa Praseodymium na Neodymium basuzumye na Mossander nk "ibintu bishya". Umwe muribo yitwaga Neodymium, yaje koroshya muri Neodymium. Ikimenyetso ND ni Neodymium.

Neodymium, Praseodymium, Gadolinium (Gá) na Samarimu (RHAN) bose batandukanijwe na Didymium, icyo gihe cyagenwe n'isi idasanzwe. Kubera kuvumbura kwabo, Didymiumi ntabwo akibikwa. Nubuvumbuzi bwabo bukingura urugi rwa gatatu kugirango ruvumbure ibintu bidasanzwe byisi kandi nicyiciro cya gatatu cyo kuvumbura ibintu bidasanzwe byisi. Ariko ibi ni kimwe cya kabiri cyumurimo murwego rwa gatatu

Neodymium, ikimenyetso cyimiti ND, sinusi ya sitland yera, nimwe mubice bidafite ishingiro ryisi, hamwe no gushonga 1024 ° C, ubucucike bwa 7.004 g /㎝, na paramagnesm.

Imikoreshereze nyamukuru:

Neodymium yabaye ahantu hashyushye kumasoko imyaka myinshi kubera umwanya wihariye mumwanya wisi idasanzwe. Umukoresha munini wa Neodymium sit ni NDfeb ibikoresho bisanzwe bya magnet. Guhiza Ndfeb muri magneti ihoraho yateye imbere imbaraga nshya mu isi idasanzwe tekinoroji ya tekinoroji yo mu rwego rwo hejuru. Ndfeb Marunet yitwa "umwami wa magnets uhoraho" kubera imbaraga zayo ndende ya magnetic.ibiri bikoreshwa cyane muri elegitoroniki, imashini nizindi nganda nizindi nganda zimikorere yacyo nziza.

Neodymium nayo ikoreshwa mubikoresho bidahuzuye. Ongeraho 1.5-2.5% Neodymium kuri Magnesuum cyangwa Aluminium ALYUGA IBIKORWA BY'IMURASIKO, gukomera ikirere hamwe no kurwanya ruswa ya alloy, kandi ikoreshwa cyane ni ibikoresho bya aerospace.

Byongeye kandi, Nettymium-Desrium aluminium Garnet itanga ibiti bigufi, bikoreshwa cyane mu gusudira no gutema ibikoresho byoroheje bifite ubunini buri munsi ya 10mm mu nganda.

Kuvura, ND: Yag Laser ikoreshwa mu gukuraho ibikomere byo kubaga cyangwa kwangiza ibisumico aho kuba scalpel. Neodymium nayo ikoreshwa mugukora amabara hamwe nibikoresho c'ikirahuri hamwe no kongeramo ibicuruzwa bya rubber.

Hamwe niterambere ryubumenyi n'ikoranabuhanga no kwaguka no kwagura isi idasanzwe nubuhanga, Neodymium izagira umwanya wagutse.

Neodymium (nd) ni icyuma kidasanzwe cyisi. Umuhondo wijimye, byoroshye okiside mu kirere, zikoreshwa mu gukora ibihuru na optique.

Hamwe n'ivuka rya Praseodymium, Neodymium yaje kubaho. Ukuza kwa Neoodymium bakoresheje umurima udasanzwe w'isi, wagize uruhare runini mu murima w'isi udasanzwe, kandi wagize uruhare mu isoko ry'isi ridasanzwe.

Gusaba Neodymium: Byakoreshejwe mugukora ceramic, ikirahuri cyiza cyijimye, ruby ​​ya artificiel muri laser hamwe nikirahuri kidasanzwe gishobora kuzura imirasire ya inzitizi. Ikoreshwa hamwe na Praseodymium kugirango ikore goggles kubirahuri. Mich icyuma gikoreshwa mubuseri kandi kirimo 18% Neodymium.

Neodymium oxide ND2 O3; Uburemere bwa molekile ni 336.40; Ifu ya Lavender, byoroshye kugira ingaruka mbi, gukurura dioxyde ya karubone mu kirere, ihungabanye mumazi, shoke muri aside inorumanic. Ubucucike ugereranije ni 7.24. Ingingo yo gushonga igera kuri 1900 ℃, kandi umurima muremure wa Neodymium urashobora gushingwa igice no gushyushya umwuka.

Ikoresha: ikoreshwa mugukora mikuruzi zihoraho, guhuza ibirahuri nibikoresho by'ubutaka n'ibikoresho bya laser.

Nanometero Neodymium oxide nayo ikoreshwa mugukomaza ibirahuri hamwe nibikoresho ceramic, ibicuruzwa bya rubber hamwe nibishyingo.

Pr-nd charct; Inzira ya molekile ni pr-d; Umutungo: Guhindura ibyuma bya feza, kurambagizanya, oroheweho byoroshye mu kirere. Intego: Byinshi bikoreshwa nkibikoresho bya magnet bihoraho.

Kurinda imiti ifite uburakari bukomeye hamwe na Mucous Membrane, kurakara bikabije kuruhu, no guhumeka birashobora kandi gutera Emyanism embolism hamwe numwijima.

Ikintu Cyibikorwa:

Kurakara amaso, uruhu, mucous membrane na tract yubuhumekero.

Igisubizo:

1. Guhumeka: Kureka urubuga mu kirere cyiza. Niba guhumeka bigoye, tanga ogisijeni. Shakisha ubuvuzi.

2. Guhuza amaso: Zamura ijisho hanyuma woge hamwe namazi atemba cyangwa umunyu usanzwe. Shakisha ubuvuzi.

3. Guhuza uruhu: Kuramo imyenda yanduye no kwoza n'amazi atemba.

4. Kurya: Kunywa amazi menshi ashyushye kugirango utere kuruka. Shakisha ubuvuzi.
